Question

我正在尝试在Ionic 4中使用Camera Plugin，并且启动服务时没有出现错误，在浏览器控制台中会出现以下错误：

我删除了node_modules文件夹并重新安装，但是无法修复。

npm安装

使用ActionSheet时，我会遇到相同的错误。

编辑：当我尝试编译它时！（使用ActionSheet）

-冗长：

ionic:cli-framework:utils:process onBeforeExit handler: process.exit received +0ms
  ionic:cli-framework:utils:process onBeforeExit handler: running 1 queued functions +6ms
  ionic:cli-framework:utils:process error while killing process tree for 8104: { Error: Command failed: taskkill /pid 8104 /T /F ERROR: no se encontr� el proceso "8104".  at ChildProcess.exithandler (child_process.js:275:12) at emitTwo (events.js:126:13) at ChildProcess.emit (events.js:214:7) at maybeClose (internal/child_process.js:925:16) at Process.ChildProcess._handle.onexit (internal/child_process.js:209:5) killed: false, code: 128, signal: null, cmd: 'taskkill /pid 8104 /T /F' } +60ms
net.js:714
    throw new TypeError(
    ^

仅当某些TS文件具有导入时，才会出现此错误。是否使用都没关系。

从“ @ ionic-native / action-sheet”导入{ActionSheet，ActionSheetOptions};

Answer 1

我已经解决了！

我需要安装@ 5.0.0-beta.17软件包。

npm i -s @ ionic-native / camera @ 5.0.0-beta.17

npm i -s @ ionic-native / action-sheet @ 5.0.0-beta.17

然后，我可以将其用于：

import { Camera, CameraOptions } from '@ionic-native/camera/ngx'; import { ActionSheet, ActionSheetOptions } from '@ionic-native/action-sheet/ngx';

确保正确安装了Camera插件和节点模块

步骤1：删除当前的节点模块，然后使用重新安装

 npm install

第2步：重建平台（删除旧平台）并安装插件

$ ionic cordova plugin add cordova-plugin-camera
$ npm install --save @ionic-native/camera

在您的TS文件中

import { Component } from '@angular/core';
import { IonicPage, NavController,ActionSheetController } from 'ionic-angular';
import { Camera, CameraOptions } from '@ionic-native/camera';
import { Storage } from '@ionic/storage';

@IonicPage()
@Component({
  selector: 'page-field-observation',
  templateUrl: 'field-observation.html',
})
export class FieldObservationPage {


 CapturedImageURL:any;


  constructor(
    public navCtrl: NavController, 
    private camera: Camera,
    public actionSheetCtrl: ActionSheetController,
    public storage:Storage
    ){



  }

  ionViewDidLoad() {
   }

captureImage() {
    const CamOptions: CameraOptions = {
      quality: 100,
      destinationType: this.camera.DestinationType.FILE_URI,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      sourceType: this.camera.PictureSourceType.CAMERA,
      targetWidth:1024,
      targetHeight:720
    }

    this.camera.getPicture(CamOptions).then((imageData) => {
      console.log(imageData);
      this.CapturedImageURL = imageData;         
  });

  }

captureImageGallery(){

  const options: CameraOptions = {
              quality: 100,
              destinationType: this.camera.DestinationType.FILE_URI,
              encodingType: this.camera.EncodingType.JPEG,
              mediaType: this.camera.MediaType.PICTURE,
              sourceType:0,
              saveToPhotoAlbum:true,
              targetWidth:1024,
              targetHeight:720,
              allowEdit:true
  }
        this.camera.getPicture(options).then((imageData) => {
          this.CapturedImageURL = imageData; 
        });
}



 CameraActionSheet() {

   let actionSheet = this.actionSheetCtrl.create({
     title: 'Choose an image from',
     enableBackdropDismiss:true,
     buttons: [
       {
         text: 'Camera',
         icon: 'camera',
         handler: () => {
            this.captureImage();
         }
       },
       {
         text: 'Library',
         icon: 'image',
         handler: () => {
           this.captureImageGallery();
         }
       },
       {
         text: 'Cancel',
         role: 'cancel',
         icon:'close-circle',
         handler: () => {
           console.log('Cancel clicked');
         }
       }
     ]
   });

   actionSheet.present();
 }


}
